Well, for starters, if he was alive i would've asked him. Point being, when you are dealing with terrorists you ought to walk a fine line. Finer than a baby's hair. You implied (if i read that correct) that some pursue such interest better than others, and since this thread is about FBI/US, i assume you meant they pursue it better?
